1600 vw motor hard to start once it's warmed up and sits.

Asked by Nov 12, 2014 at 01:30 PM about the 1974 Volkswagen Beetle

Question type: Maintenance & Repair

1974, 1600 vw w/pict34-3 starts easy when cold, runs very good.  Will start up right after it's shut off, but after it sits for 5-10 minutes it's very hard to start and runs very rich.  I have adjusted the valves, set the timing to 32 BDC, replaced plugs, rebuilt carb, float was fine.  What's next, new carb?  It runs great once it starts.

I would think carburator had time to set after warm,and fuel pressure up,the carb is flooding and that may be your issue,replace carburator.

It's the plastic piece that drops in below the fuel pump that guides the rod for the fuel pump. Once it gets hot it swells up and holds the fuel rod up. There is videos on YouTube how to sand that piece. I believe they call it vapor lock or something. Once you sand it should take care of it. I'm converting mine to a 3.5 PSI eltronic fuel pump with a safety switch on the oil pressure cause the local auto parts fuel pumps keep going out on me every few months due to the hot heat in Florida and the ethenal in the fuel messing up the digram.
